ROLLER-SKATE..

SPECIFICATION forming part of Letters Patent No. 326,261, dated September 15,1885.

Application tiled July 14, 1885. (No model.)

To all whom, t may concern.-

Beit known that I, HOLLIS W. BARROWS, a citizen of the United States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Boller-Skates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

One great fault with the tension-plates now in use is the fact that they rock on the point of the single set-screw used and do not adjust the rubber spring at all, or they fail to compress it uniformly and level up the truck.

My invention consists in providing a hinged or two-part tension-plate-that is, aplate cornposed of two steel plates, whose inner edges abut together or are slightly apart, as the case may be, each `of said plates being provided with Opposite teats, which play in guides or grooves in the hanger-posts, and also being each provided with a lateral depending flange for holding the rubber spring properly or preventing it from falling out. To adjust the above plate, a set-screw is provided for each portion, which may operate through the soleplate or below it.

In the drawings, Figure 1 is a side elevation, one roller being removed. Fig. 2 is aplan view in broken section, the sole-plate being reversed and the spring and truck removed. Fig. 3 is a detail view of the tension-plate.

Like letters refer to like parts.

The general form of the skate being well known, it needs no detailed description.

A represents the sole-plate; B, the hanger, and C the truck. On the pintlefshelf D of the truck rests a square rubber spring, E, and over this is the tension-plate F. Said plate consists of two steel plates, ff, (see Fig. 3,) each of which is provided with opposite teats a a and a lateral depending ange, b. The meeting edges of the plates f f should abut together, or nearly so. As the plates are pressed down upon the rubber spring the teats are held and guided by grooves ce in the hangerposts B B', which grooves should extend to the bottom of the posts. This tongue-andgroove construction lholds the two-part plate together and causes it to act as a hinge, while the side langes will keep the spring from falling out. By having the two plates f f hinge at their meeting edges, either plate may be adjusted on the spring to level up the truck, which the ordinary tension-plate in use often fails to do.

' Passing through the web B2 of the hangerposts are set-screws g gone for each of the plates f f. These screws may be operated through a hole, m, in the sole-plate, Or from below, as the form of the skate used may dictate.

My improvement is simple and effective, and can be applied to any of the forms of skates now used with little trouble or alteration.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the rubber spring, of a hinged or two-part tension-plate and setscrews for adjusting each division of said plate, as set forth.

2. The combination of the tension-plate, consisting of two portions, each provided with opposite tongues, with the hanger-posts having a corresponding groove or guide, the rubber spring, the truck, and set-screws for adjusting each division of the plate, as set forth.

3. The combination of the tension-plate, consisting of two separate plates, each provided with opposite tongues and a lateral depending ange, with the hanger-posts having a groove to hold and guide said tongues, the rubber spring, the truck, and set-screws, operated through or below the sole-plate, for adjusting each division of the plate, as set forth.

4. A two -part tension plate having the meeting edges of the divisions terminating in opposite tongues, combined with the hangerposts provided with a corresponding groove, the rubber spring, the trucks, and the setscrews, whereby the plate acts as a hinge, or either division may be adjusted to level up the truck, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
